dialysis catheter is a catheter used for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens: venous and arterial.
Although both lumens are in the vein, the “arterial” lumen, like natural arteries, carries blood away from the heart, while the “venous” lumen returns blood towards the heart.
long-term dialysis therapy, a chronic dialysis catheter will be inserted. Chronic catheters contain a Dacron cuff that is tunneled beneath the skin approximately 3–8 cm.
The tunnel is thought to add a barrier to infection. The most popular dialysis catheter sold on the market today is the Symmetrical-Tip dialysis catheter.
